Created attachment 1842908 [details] kernel-5.14.18 dmesg 1. Please describe the problem: After upgrading to kernel 5.12.x, I started getting these errors in dmesg: [ 4.070813] kernel: nouveau 0000:01:00.0: ce: ucode exceeds falcon limit(s) [ 4.070815] kernel: nouveau 0000:01:00.0: ce: init failed, -22 [ 4.070818] kernel: nouveau 0000:01:00.0: bus: MMIO read of 00000000 FAULT at 10312c [ PRIVRING ] [ 48.235115] kernel: nouveau 0000:01:00.0: bus: MMIO read of 00000000 FAULT at 103048 [ PRIVRING ] 2. What is the Version-Release number of the kernel: All kernels starting from 5.12.6-300.fc34.x86_64 and up to 5.14.18-300.fc35.x86_64 3. Did it work previously in Fedora? If so, what kernel version did the issue *first* appear? Old kernels are available for download at https://koji.fedoraproject.org/koji/packageinfo?packageID=8 : Yes. The errors are not present under 5.11.21-300.fc34.x86_64 or earlier. 4. Can you reproduce this issue? If so, please provide the steps to reproduce the issue below: Yes. Boot the system with 5.12.x or newer kernel. 5. Does this problem occur with the latest Rawhide kernel? To install the Rawhide kernel, run ``sudo dnf install fedora-repos-rawhide`` followed by ``sudo dnf update --enablerepo=rawhide kernel``: No. It seems to be fixed in 5.16-rc1. Upstream bug report says the same. 6. Are you running any modules that not shipped with directly Fedora's kernel?: No. 7. Please attach the kernel logs. You can get the complete kernel log for a boot with ``journalctl --no-hostname -k > dmesg.txt``. If the issue occurred on a previous boot, use the journalctl ``-b`` flag. Attached.
FWIW, kernel-5.15.3-200.fc35 from koji doesn't show these errors, either.
